How oak trees outwit their predators
What to know about How oak trees outwit their predators
A study published in Nature Ecology & Evolution details how oak trees delay their leaf emergence by three days following heavy caterpillar infestations. Researchers used satellite data over a 2,400-square-kilometer area to demonstrate that this biological response is a highly effective defense mechanism, fundamentally changing previous understandings of forest spring dynamics. The findings suggest that biological interactions, such as insect pressure, are as critical to forest health as temperature alone.
